Originally, the Guilds attending the Blackwing Auction had already given up on bidding for the final item. They merely stayed to take a look at how high the price of the final item would reach.
The minimum price for the item was 30 Gold. None of the Guilds present were that flush with fluid funds.
However, the moment their sights landed on the final item, they instantly had a change of heart.
The reason being, the item displayed on stage was simply too important to a Guild. The final item was neither weapon nor equipment. Instead, it was a Forging Design. If the Forging Design was for a normal weapon or equipment, nobody would have paid any attention to it.
However, the Forging Design being auctioned was for the Arclight Shield, a Level 15 Fine-Gold ranked shield. If they could produce this item, it would definitely provide a huge improvement for the MTs in their Guilds. This shield was especially useful during this crucial period of the game.
